ABSTRACT

OBJETIVOS: Avaliar os resultados funcionais iniciais e o índice de complicações precoces das artroplastias totais do quadril cerâmica-cerâmica em pacientes que convivem com o HIV e apresentam osteonecrose da cabeça femoral. MÉTODO: Doze pacientes HIV+ com diagnóstico de osteonecrose da cabeça do fêmur incongruente foram avaliados através de critérios clínicos, laboratoriais, pela escala funcional WOMAC antes e após o tratamento com substituição articular. RESULTADOS: Observamos que 83,3% dos indivíduos faziam uso de inibidores de protease, 75% apresentavam dislipidemia e 66,6% síndrome lipodistrófica, a melhora na evolução no escore WOMAC foi estatisticamente significativa para seis e 12 meses de pós-operatório em comparação com o escore pré-operatório e não observamos complicações secundárias a esse procedimento. CONCLUSÃO: A artroplastia total do quadril com implante de cerâmica-cerâmica para o tratamento da necrose avascular do quadril nessa parcela da população é opção cirúrgica adequada, apresenta melhora funcional inicial significativa e baixo índice de complicação precoce.


OBJECTIVES: To evaluate the initial functional results and early complication rate of ceramic-ceramic total hip replacements among patients living with HIV who presented osteonecrosis of the femoral head. METHOD: Twelve HIV-positive patients with a diagnosis of osteonecrosis of the incongruent femoral head were evaluated using clinical and laboratory criteria and the WOMAC functional scale before and after treatment with joint replacement. RESULTS: We observed that 83.3% of the subjects were taking protease inhibitors, 75% had dyslipidemia and 66.6% had lipodystrophy syndrome. The improvement over the evolution of the WOMAC score was statistically significant at six and twelve months after the operation, in comparison with the preoperative score. We did not observe complications secondary to this procedure. CONCLUSION: Total hip arthroplasty with a ceramic-ceramic implant for treating avascular necrosis of the hip is an appropriate surgical option for this portion of the population. It provides a significant initial functional improvement and a low early complication rate.

ABSTRACT

OBJETIVO: Analisar as características epidemiológicas e tendências quanto à incidência de TB pleural. MÉTODOS: Estudo descritivo, retrospectivo dos casos de TB reportados entre 1998 e 2005 e coletados do banco de dados do Sistema de Notificação de Tuberculose (Epi-TB) da Secretaria de Saúde do Estado de São Paulo. RESULTADOS: Foram notificados 144.347 casos novos de TB durante o período estudado. A forma pulmonar foi predominante (118.575 casos; 82,2 por cento). Das formas extrapulmonares (25.773 casos; 17,8 por cento), a pleural foi a mais referida (12.545 casos; 48,7 por cento). A incidência (por 100.000 habitantes) de todas as formas diminuiu, (49,7 em 1998 e 44,6 em 2005; R² = 0,898; p < 0,001), enquanto a incidência de TB pleural permaneceu estável (4,1 em 1998 e 3,8 em 2005; R² = 0,433; p = 0,076). A maior incidência de TB pleural ocorreu em pacientes do sexo masculino (2:1) entre 30 e 59 anos de idade. Dos 12.545 pacientes com TB pleural, 4.018 (32,0 por cento) apresentaram comorbidades: alcoolismo (9,5 por cento); HIV (8,0 por cento); diabetes (3,3 por cento); e doença mental (1,2 por cento). O diagnóstico referido fundamentou-se em métodos bacteriológicos (14,2 por cento) e histológicos (30,2 por cento), assim como outros não especificados (55,6 por cento). CONCLUSÕES: No estado de São Paulo, a TB pleural foi a forma extrapulmonar predominante, apresentando incidência estável no período entre 1998 e 2005, apesar da tendência de diminuição das formas pulmonares. A histologia e a bacteriologia definiram o diagnóstico em 44,4 por cento dos casos.


OBJECTIVE: To analyze the epidemiological characteristics of and trends regarding the incidence of pleural TB. METHODS: This was a retrospective descriptive study of TB cases reported between 1998 and 2005 and compiled from the Epidemiological Surveillance Tuberculosis System (Epi-TB database). RESULTS: A total of 144,347 new cases of TB were reported during the period studied. Pulmonary TB was the predominant form (118,575 cases; 82.2 percent). Among the extrapulmonary forms (25,773 cases; 17.8 percent), pleural TB was the form most often reported (12,545 cases; 48.7 percent). For all forms, the incidence (per 100,000 population) decreased (from 49.7 in 1998 to 44.6 in 2005; R² = 0.898; p < 0.001), whereas the incidence of pleural TB remained stable (4.1 in 1998 and 3.8 in 2005; R² = 0.433; p = 0.076). The highest incidence of pleural TB was found among males (2:1) aged from 30 to 59 years. Of the 12,545 patients with pleural TB, 4,018 (32.0 percent) presented comorbidities: alcoholism (9.5 percent); HIV (8.0 percent); diabetes (3.3 percent); and mental illness (1.2 percent). The diagnosis was based on bacteriological (14.2 percent) and histological (30.2 percent) methods, as well as on unspecified methods (55.6 percent). CONCLUSIONS: Pleural TB was the predominant extrapulmonary form of TB in the state of São Paulo, with a stable incidence between 1998 and 2005, although there was a trend toward a decrease in the incidence of the pulmonary forms. The diagnosis of pleural TB was confirmed through histology and bacteriology in 44.4 percent of the cases.

ABSTRACT

The pandemic novel influenza A (H1N1) infection was considered widespread in Brazil on July 16, 2009. Since then, 46,810 cases of acute respiratory syndrome have been reported in Brazil, most of them concentrated in São Paulo. Through September 16, we have confirmed 9,249 cases of novel influenza A H1N1in Brazil, including 699 deaths. The mortality rate observed in Brazil is 0.47/100,000 inhabitants and varies according to region. In this period, São Paulo registered 3733 cases (40.3 percent of the total) of novel influenza A (H1N1) infection and 327 deaths, reflecting a mortality rate of 0.79/100,000 inhabitants. The Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC) is a reference center for H1N1 cases in São Paulo. During the winter of 2009, 472 patients in this hospital were diagnosed with H1N1 infection; of these, 210 were admitted, and 16 died. To control this pandemic and to provide adequate care for these patients, the Hospital das Clínicas implemented "bundles" including prevention strategies, an epidemiologic surveillance service, availability of fast diagnosis, antiviral treatment and training of staff. The purpose of this manuscript is to describe the epidemiologic features of novel human influenza A (H1N1) infection in the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo during the winter period of the 2009 pandemic.

ABSTRACT

FUNDAMENTO: Identificar os fatores de risco para complicações pós-operatórias do paciente cardiopata com indicação cirúrgica que podem influenciar na decisão sobre a conduta terapêutica. OBJETIVO: Descrever a experiência de um hospital de Cardiologia na validação e uso prático de um escore de risco pré-operatório. MÉTODOS: Para validação do escore escolhido (Tuman), avaliaram-se consecutiva e prospectivamente 300 pacientes adultos antes da cirurgia cardíaca eletiva com o uso de circulação extracorpórea (CEC). Pacientes com escore de 0 a 5 foram considerados de baixo risco; de 6 a 9 como risco moderado; e maior que 10, como alto risco para complicações cardíacas, infecciosas, neurológicas, pulmonares e renais, além de óbito. RESULTADOS: A classificação de Tuman mostrou relação estatisticamente significante com ocorrência de complicações infecciosas (p=0,010), com outras complicações pós-operatórias (p=0,034) e com evolução para óbito (p<0,001). Infecção pulmonar foi a mais freqüente dentre as complicações infecciosas (15,3 por cento), Os pacientes infectados tiveram maior tempo de permanência na UTI (p=0,001) e internação mais prolongada (p=0,001). Após o uso rotineiro, uma nova avaliação de 154 pacientes operados em 2005 confirmou a validade desse escore na identificação daqueles com maior risco de infecções pós-operatórias. CONCLUSÃO: Escolheu-se o escore de Tuman por envolver variáveis de fácil obtenção, por classificar no mesmo sistema as cirurgias mais freqüentemente realizadas e prever risco de complicações pós-operatórias, além da mortalidade. Seu uso continuado nesse hospital permitiu identificar o grupo de pacientes com maior risco de complicações, especialmente as infecciosas, mas não foi preciso na predição do risco individual.


BACKGROUND: The identification of risk factors for postoperative complications in cardiac patients with surgical indication may influence the therapeutic decision. OBJECTIVE: To describe the experience of a Cardiology hospital in the validation and practical use of a preoperative risk score. METHODS:To validate TUMAN's score, chosen by considering morbidity and mortality, 300 adult patients were prospectively evaluated before elective cardiac surgery with the use of extracorporeal circulation (ECC). Patients with a score of zero to five were considered as being low risk; from six to nine, as moderate risk and a score higher than 10 as high risk for cardiac, infectious, neurological, pulmonary and renal complications, as well as death. RESULTS: The TUMAN classification showed a statistically significant association with the occurrence of infectious complications (p = 0.010), with the other postoperative complications (p = 0.034) and death (p <0.001). Pulmonary infection was the most frequent infectious complication (15.3 percent) and Infected patients had a longer ICU stay duration (p = 0.001) and more prolonged hospitalization (p = 0001). After routine use, a new review of 154 patients operated in 2005, confirmed the validity of this score in the identification of those with the highest risk of postoperative infections. CONCLUSION: TUMAN's score was chosen as it uses variables that can be promptly obtained, classifies in the same system the most frequently performed surgeries and predicts risk of postoperative complications, in addition to mortality. Its continued use in this hospital has been able to identify the group of patients with increased risk of complications, especially infectious ones, although it was not useful in the prediction of individual risk.

ABSTRACT

INTRODUCTION AND OBJECTIVES: Tuberculosis and cancer are the main causes of pleural effusion. Pleural involvement is associated with migration of immune cells to the pleural cavity. We sought to characterize the immunophenotype of leukocytes in the pleural effusion and peripheral blood of patients with tuberculosis or malignancy. METHODS: Thirty patients with tuberculosis (14) or malignancy (16) were studied. A control group included 20 healthy blood donors. RESULTS: Malignant phycoerythrin pleural effusions showed higher percentages of CD3, CD4, CD3CD45RO, and CD20CD25 lymphocytes and lower percentages of CD3CD25 and CD20HLA-DR when compared to PB lymphocytes. Compared to PB, tuberculous effusions had a higher percentage of lymphocytes that co-expressed CD3, CD4, CD3CD45RO, CD3TCRáâ, CD3CD28, and CD20 and a lower percentage of CD14, CD8 and CD3TCRãä-positive lymphocytes. Malignant effusions presented higher expression of CD14 whereas tuberculous effusions had higher expression of CD3 and CD3CD95L. Peripheral blood cells from tuberculosis patients showed higher expression of CD14, CD20CD25 and CD3CD95L. Compared with the control cells, tuberculosis and cancer peripheral blood cells presented a lower percentage of CD3CD4 and CD3CD28-positive cells as well as a higher percentage of CD3CD8, CD3CD25 and CD3CD80-positive cells. CONCLUSIONS: Tuberculous and malignant peripheral blood is enriched with lymphocytes with a helper/inducer T cell phenotype, which are mainly of memory cells. CD14-positive cells were more frequently found in malignant effusions, while CD3-positive cells expressing Fas ligand were more frequently found in tuberculous effusions.

ABSTRACT

Early identification of an outbreak is one of the main advantages of routine epidemiological surveillance. Enterococcus spp. used to be regarded as microorganisms of low pathogenicity, because they are part of the normal microbial flora of the gastrointestinal and genitourinary tract. Recently, they have emerged as important pathogenic agents, sometimes causing infections with high mortality rates. We studied a clustering of primary bloodstream infections caused by Enterococcus faecalis in a cardiology hospital neonatal intensive care unit (NICU). Four cases of primary bloodstream infection by E. faecalis were detected from April 15 to May 13, 2004, during active infection surveillance. The isolates were sensitive to glycopeptides. Some aspects of the management of these patients, including the date of insertion and placement of a central venous catheter, prescription of a specific medication, contiguity of beds, personnel attending the patients, and occurrence of diarrhea were analyzed to look for factors that might affect the spread of the microorganisms. Measures taken to hamper the spread included contact precautions throughout the unit, cleansing and disinfection of equipment and surfaces, bathing children with 2 percent chlorhexidine-gluconate-containing soap, professional reeducation, and reinforcement of all measures to prevent infections. We suggest that there is a need to re-evaluate preventive infection measures and to review the strategies aimed at decreasing the nosocomial infection rate in the NICU.

ABSTRACT

Esta edição , que anuncia a Mesa Redonda sobre Co-infecçoes AIDS e Hepatite B e C, não só nos convida a fazer uma série de reflexões, como acabou transformando-se em uma verdadeira aula sobre a situação atual em nosso País, com propostas para a ação individual e coletiva do Setor Saúde como um todo. O local nao poderia ser mais feliz, o recem-inaugurado Centro de Pesquisa em Saúde, o CEPES, da Faculdade de Medicina do ABC. Os Drs. David Uip, Hoel Sette Jr., Roberto Focaccia e Maria Cassia Mendes Correa, além do altissimo nível dos debates, mantiveram durante toda a reunião uma atitude ousada, provocativa, questionando os seus próprios conhecimentos cientifícos com a sua vivência, do seu dia a dia na linha de frente da luta contra a AIDS e a hepatite. Podemos afirmar que ao término da reunião, todos os presentes sentiam que não se encerrava um debate, mas sim que algo novo começava a ser criado. Os debatedores não se limitaram a fazer as suas conclusões finais, mas plantaram idéias fundamentais que, sem duvida, vão nortear as açoes futuras que se fazem necessarias para colocar o nosso País, mais uma vez, em posição de destaque no campo da Medicina

ABSTRACT

134 pacientes com fraturas expostas dos membros inferiores dos tipos II, IIIA, IIIB e IIIC foram estudados prospectivamente entre fevereiro de 1998 e maio de 2000 no Instituto de Ortopedia e Traumatologia da Faculdade de Medicina da Universidade de São Paulo para determinar os fatores de risco de infeccão previsíveis Todos os pacientes foram registrados em um protocolo no qual eles tiveram amostras de fragmentos ósseos iniciais coletadas para cultura bacteriana, avaliacão de condicões clínica e administracão precoce de antibiótico. Durante a abordagem inicial, as causas das fraturas, o tempo de exposicão da fratura e o local onde os primeiros socorros foram recebidos foram observados. Durante o debridamento inicial, o volume de transfusão sangüínea, a classificacão clinica ASA, o tempo cirúrgico, o ferimento cirurgico e o tipo de estabilizacão esquelética foram observados. Uma análise univariável foi realizada para identificar os riscos pervisíveis estatisticamente significantes para o desenvolvimento de infeccões, com os seguintes resultados: tempo de exposicão da fratura (p=0.0201), local dos primeiros socorros (p=0.400), tipo de fratura (p=0.0130), classificacão ASA (p=0.0005), volume de transfusão de sangue (p=0.0002) tipo de osso fraturado (p=0.0052), tipo de acidente (p=0.0450), ferimento cirúrgico (p=0.0024), estabilizacão esquelética (p=0.0446), cultura bacteriana positiva na admissão (p=0.5290) e cirurgias concomitantes (p=0.1867). As variáveis com associacão significante com a infeccão foram introduzidas em uma equacão de regresão multivariada (modelo logístico) para identificar as com efeitos independentes dos outros fatores. O modelo logístico final foi obtido e demonstrou as probabilidades de infeccão nas fratruras expostas estudadas. Os riscos relativos revelados no modelo logístico final foram : volume de transfusão sangüínea (mais do que 1 unidade) - 6.4;classificacão ASA nível III - 5.2; fixacão interna do osso (imediata) - 3.9; osso fraturado (femur) - 3.5 and ferimento aberto - 3.0.

ABSTRACT

HIV-infected women from S o Paulo city were enrolled in a cross-sectional study on Human Papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN) prevalence and their association with laboratory markers of AIDS, namely HIV viral load and CD(4)(+) cell counts. A cervical specimen was collected and submitted to Hybrid Capture, a test for HPV viral load determination. HPV-DNA was detected in 173 of 265 women (64.5). Twenty (7.5) women were infected by one or more low-risk viruses, 89 (33) by one or more high-risk viruses, and 64 (24) harbored at least one HPV type from each risk group. Abnormal smears were observed in 19 of the patients, though there were no invasive carcinomas. Severely immunosuppressed patients (CD(4)/microL <100) were at the greatest risk of having a cytological abnormality and a high high-risk HPV viral load.
